Position data of target points (26', 26', . . . ) in a target area (21) is generated based on the position data of the target area (21) (position data of a borderline (20)) inputted to area data input device (3). A vehicle (13) is sequentially guided to travel through the target positions (26', 26', . . . ) in the target area (21) while being given the position data of the target points (26', 26', . . . ). Not by a conventional method such as a teaching method, a travel course to target points in a target area is easily created with little man-hour in a short time when an earth unloading area (target area) which the vehicle is to reach is given, thereby enhancing the work efficiency of creating a travel course. Further, target earth unloading points in an earth unloading area are arranged uniformly and densely, and consequently the efficiencies of an earth unloading work and a leveling work are enhanced. |
